Scalable Hybrid Antibacterial Surfaces: TiO Nanoparticles with Black Silicon.

With the increase of drug resistance, there is a need for surface coatings that inhibit microbes without antibiotics. Nanostructured photocatalysts, like TiO-coated nanotubes, are promising alternatives to antibiotics. Nanostructures rupture the cell wall by impaling the bacteria.

Ambient Light-Activated Antibacterial Material: Manganese Vanadium Oxide (MnVO).

Antimicrobial surfaces can reduce the spread of bacteria from high-touch surfaces, saving millions of lives worldwide. Antibacterial photocatalytic films, like TiO, are widely reported but limited in practice because they need high-intensity UV light. More practical but less reported are photocatalysts that work under low-intensity visible light from an indoor lamp.
